Both admit objective analysis, so how is either any more real than the other? You might argue 17 is less real because we can't access it with our senses, but neither can we access the insides of stars with our senses. Yet no one disputes the reality of the insides of stars. You might argue the chair is more real because we can affect it, but then you would have to conclude the anything outside our light cone is not real, for we cannot affect anything outside our light cone. Also, how do you know the chair is anything more than a pattern in a brain process? Jason -- You received this message because you are subscribed to the Google Groups "Everything List" group.
